I figured out why 3035 was not working for me. The problem was tmux. The tmux server was somehow preventing the shell from getting the signal that I was done in sublime text. For me the solution is to use the reattach-to-user-namespace command as described here: https://github.com/ChrisJohnsen/tmux-MacOSX-pasteboard I'm not sure this is the best solution, but it works. If other tmux users have run across this problem and have a better solution I would be happy to hear about it.
